GREAT system Mark! I used to own the B&W 804S a while ago and it was paired up with Classe, a very nice combination indeed. I understand the Diamonds are awesome! I am also a big supporter of what the PS Audio products can do. I have the P3 and have been very happy with the improvements. I experimented with Stillpoint Minis and Ultras under all my components and speakers and found that they made the most impact under the PS Audio P3. Do you have your amps powered by the P10? That being said, I need to revisit the Stillpoints because since I have added room treatments I can more clearly hear changes to my system.
Again very nice system!
